James Cameron Deep Sea Challenge

On March 26th 2012, James Cameron successfully reached the bottom of the world’s deepest part of the ocean, the Marianas Trench, 10.99 kilometres below the surface.

The pressure at this depth is around 16,000 PSI and it was a Blanson manufactured acrylic window that was chosen for the task.

Filming was performed through the window which was designed and machined in such a way as to correct for the 30-percent magnification effect of water.
The strength and optical clarity of the window was therefore of critical importance to ensure both the safety of James Cameron and the quality of the filming.
